BUFORD J. STEEN, OF GOOSE CREEK, TEXAS.

PIPE-WRENCH.

This invention relates t0 new and useful,

improvements in a pipe wrench.

One object of the invention is to provide a wrench of the characterdescribed, adapted t0 be used for screwing sections of pipe together,and for unscrewing them. However, the wrench may be used for othersimilar purposes to which it may be applicable.

Another object of the invention resides inthe provision of a wrench ofthe character described, which is of simple and cheap construction, andmay be easily manipula-ted to turn the pipe sections in either directionin screwing them together, or separat- A further feature of theinvention resides in the provision of a wrench which may be readilyreleased from the pipe or other object which may be engaged thereby.

With the above and other objects in view, the invention has particularrelation to certain novel features of construction, arrange-` ment ofparts and use, an example of which isA given in this specification and.illustrated in the accompanying drawings, wherein:

Figure l, is a side view of the wrench, and

Fig. 2, is a plan view thereof.

Referring now more particularly to the drawings' wherein like' numeralsof reference designate similar parts in each of lthe figures, thenumeral 1 refers to a Wrench handle, whose operative end is formed intothe arcuate gripping jaws 2 and 3. The jaw 2 is provided on its innerside, `with a recessed bearing 4, wherein the dog 5 is pivoted. Theouter end of this dog is toothed, and the dog is seated against the coilspring 6, which operates to hold it projected from the jaw and intoengagement Speccation of Letters Patent.

Application l'ed March 4, 1919. Serial No. 280,538.

may be released from the pipe. The jaw 2 3, near its base, has asimil'ar dog 7, which is held projected against the pipe by nieans ofthe coil spring 8, and near the free end of the jaw 3, there isa similardog`9, whose outer or operative face is toothed'to engage with the pipe,and which is held in engagement therewith by means of the coil spring10.4 When the wrench is applied to the pipe, IJthe dog 9 will -pass morethan half of the Way around the pipe from the dog 5. Should the handle 1be then moved in the direction indicated by the arrow, said dogs willengage with the.. pipe and turn same. In order to release the wrenchfrom the pipe, I have provided a release rod 11, which is attached atone end to the inner end of the dog 9, and which projects out throughthe slot 12, out through the jaw 3. Vhen this rod is pulled in thedirection toward the free end of the jaw 3, it will release the ydog 9from the pipe and the wrench may be then disengaged from said pipe. Byreversing the wrench in itsapplication to the pipe, said pipe may beturned in the other direction, the wrench thus being adapted for use ineither screwing or unscrewing pipe.

What; I claim is:

A wrench including a handle, a pair of opposed arcuate .jaws integralwith the handle adapted to embrace a pipe, there be.- ing recesses inthe walls of said arcuate jaws and slots communicating from certain ofsaid recesses to the outer surface of the jaws, a dog pivotally mountedin each of said recesses adapted to grip the pipe, and handlesintegrally formed with certain of said dogs and protruding through saidslots whereby the dogs can be manipulated by hand during operation andsprings urging said dogsto grip the pipe.

In'testimony whereof I have signed my.

n ame to this specification in thepresence of two subscribing witnesses.
